Question

I’m passing parameters to a server from a Flash Builder application. I want to search both for “teachers” and for “rooms”. I can do this via an HTML page, as follows:

<input type="checkbox" name="searchFor" value="teachers" />teachers 
<input type="checkbox" name="searchFor" value="rooms" />rooms 

So there are two inputs, both named searchFor. When submitted, the request looks like this:

searchFor: teachers
searchFor: rooms

In other words, two parameters are passed.

I’m trying to do the same thing in Flash Builder using an object called param:

param.query = pQuery;
param.searchFor = "teachers";
param.searchFor = "rooms";
searchUsersService(param); 

Flex overwrites the one with the other, as I suspected it would, so all that is submitted is “rooms”. Is it possible to pass two parameters with the same name? (or do I need to ask the server guys to rename their search parameters?)

Thanks.

Answer 1

You can’t. It will only override the previous value:

param.query = pQuery;
param.searchFor = "teachers";
param.searchFor = "rooms";    //Will obviously override the previous value
searchUsersService(param); 

What you can do is:

param.searchFor = [ "teachers", "rooms" ];

Or

param.searchFor = new ArrayCollection();
param.searchFor.add( "teachers" );
param.searchFor.add( "rooms" );

And then in the server side you can get all the values from your array.
